Wireless charging is a seldom used but very promising piece of mobile technology and NuCurrent’s newly announced 10 watt multi-mode wireless charging antenna is another step towards making the technology much more popular.

The new NuCurrent antenna assembly supports wireless charging standards from both the Wireless Power Consortium and the recently formed AirFuel Alliance. Multi-mode technology, such as the PMA/Qi implementation found in the Galaxy S6, is seen by some as key to improving wireless charging adoption. However NuCurrent’s design goes one step further by supporting both inductive and resonance based charging methods.

“This new series of NuCurrent products truly realizes our vision of ‘future proofing’ next generation wireless charging and offers differentiation in smartphone design,” – Michael Gotlieb, vice president of business development, NuCurrent

The receiver antenna provides nearly 80 percent energy transfer efficiency at 10 watts using its inductive Qi coil. There is also a 10 watt A4WP resonator on the same substrate, which supports orientation-free placement and longer charging distances. The hardware fits into just a 0.3 millimeter thick package, allowing for thin, low heat implementations.

While wireless power transfer obviously won’t be as efficient as a wired cable, anywhere between 6 and 8 watts should provide enough current to charge up a smartphone at least as quickly as using a non-fast charging wall plug. Slow charging speeds have previously been one limiting factor preventing common adoption of wireless charging.

NuCurrent has been demonstrating its new antenna at the Wireless Power Summit on California today and yesterday. Hopefully we will see a few smartphones sporting the technology appear in the near future as well.


NuCurrent Delivers World’s First 10+ Watt, Ultra-thin, Qi / A4WP Wireless Charging Smartphone Antenna

New multi-mode antennas deliver the highest Q Factor, lowest heat at 0.3mm thinness for medium power applications

(CHICAGO – November 5, 2015) – NuCurrent, a leader in wireless power antenna technology, announces the world’s first ultra-thin, fast charging, 10 watt multimode wireless charging antenna assemblies (coil + ferrite). As the first of its series, the antenna targets ultra-thin, battery maximizing smartphones and other functionality rich connected devices. With the release, NuCurrent delivers a full production version A4WP + Qi phone receiver antenna which provides nearly 80 percent efficiency at 10 watts with its Qi coil, combined with a 10 watt, fully uniform, orientation-free A4WP resonator on the same 0.3 millimeter printed substrate.

“This new series of NuCurrent products truly realizes our vision of ‘future proofing’ next generation wireless charging and offers differentiation in smartphone design,” said Michael Gotlieb, vice president of business development, NuCurrent. “From a systems perspective, this series of break-through antennas finally bridges the gap between all the standards in an environment hungry for space and power.”

The new, certifiable NC21-R76M13E-87670R30 enables fast charging with lower heat due to the use of NuCurrent patented technology, design expertise and proprietary modeling. Supporting standards from Wireless Power Consortium (Qi) and AirFuel™ Alliance (previously A4WP/PMA), NuCurrent again shows it market leadership in thinness, Q Factor and design with a 10W product ready for immediate production or customization.

NuCurrent will be demonstrating its leading, high-efficiency antennas at the upcoming Wireless Power Summit, to be held November 5-6 in San Diego, California.
